Who laid out this ship? It seems all wrong; for one the guest quarters are only accessible from the aft stairwell which comes out in the Engine Room? I wouldn’t want guests to have access to that area. I would suggest that we change that area to storage areas and maybe and armory.
Change rooms 26-28 into one room, quarters for the Mechanic. I would think room #4 (currently medical) should be either the Captains quarters; the medical should be on the cargo deck as carrying wounded up a circular stairwell is not practical. Maybe take part of the aft Cargo Bay and divide off a third for the Medical with a separate entrance.
I like the suggestion of the Missile Turret being converted into a Hover Bike hanger; my character can call dibs on that item
Anyway, just a couple of suggestions.
